摘要:建筑工程是一项协同多参与方的组织活动，在项目全寿命周期各个阶段都会有各种信息流的相互传输。目前，由于主客观因素在建筑全寿命周期中经常会出现信息传输的失真，即“信息孤岛”现象，该现象大大制约了项目的高效进展，BIM技术的出现为解决该问题提供了有效工具。在建筑工程项目协同机制进行需求分析的基础上，建立以BIM技术为核心的建筑工程项目协同模型，分析建筑工程项目协同模型运用实际工作中需要注意的问题并提出几点意见，为建筑全寿命周期工作流程再造和提高项目效率提供了基础。

Abstract: The construction project is a collaborative multi-party organization activity, and each phase of the project life cycle has mutual transmission of information flow. At present, due to the subjective and objective factors in the life cycle of the architecture, there is often distorted information transmission, namely "the information isolated island" phenomenon. This phenomenon has greatly restricted the effective progress of the project, while the appearance of BIM technology provides an effective tool for solving the problem. Based on demand analysis, in the construction project collaborative mechanism, this paper establishes the construction project based on BIM technology as the core of the coordination model, analyzes the problem of construction project collaborative model in the actual work and puts forward some solutions, and provides the basis for building life-cycle process reengineering and improve the efficiency of the project.
